Product Details

The JE Pistons 314700 is a forged 2618 aluminum piston set engineered for high-horsepower Ford Modular 5.4L 4-valve applications. Built around JE's dedicated Forged Side Relief (FSR) forging design, this set delivers an exceptional balance of lightweight construction and race-proven durability suited for both street performance and competition use.

The FSR forging design strategically removes mass in low-stress areas while reinforcing high-load zones, resulting in a piston that is both lighter and stronger than traditional designs. Each piston features a -7.5cc inverted dome/dish crown with precision-machined valve reliefs to accommodate aftermarket camshafts with aggressive lift profiles.

A key advantage of this set is the raised compression height (1.320 in. CD), which positions the piston crown closer to the top of the deck. This improvement over stock geometry significantly enhances combustion efficiency and flame travel for more complete cylinder burn.

Wow that was fast. I ordered a Pertronix Ignitor conversion kit. Not only were they by far the lowest price I could find, they shipped within hours of submitting the order. I got the shipment in less than 24 hrs, even though I ordered ground shipping. I was a little bummed that they did not offer free shipping, as I am used to with other online places, but with their fast turnaround, I am not begrudging it. Sure it might have been because they have a warehouse nearby, but it was still unexpectedly impressive. The part arrived and looks like it all there and should be good to go. <br><br>I can't vouch for their customer service, but so far I am pleasantly surprised.

quick, easy, no-hassle experience.

Great price on a hard to find item. Lightning fast shipping with same day service, wow!!!
